How were the switches designed such that they prevented accidental activation? Because it looks like they just get simply flipped down. Could it be pull-out-and-down? Or maybe there’s a lot of resistance during the switch action?
The lever-lock fuel switches are designed to prevent accidental activation - they must be pulled up to unlock before flipping, a safety feature dating back to the 1950s. This isn’t a new or weird design. It’s essentially the standard used in basically every plane because it works.
“It would be almost impossible to pull both switches with a single movement of one hand, and this makes accidental deployment unlikely,” a Canada-based air accidents investigator, who wanted to remain unnamed, told the BBC.
